What is MainStage?

MainStage is a music application designed for use in live performance. MainStage turns your computer into a powerful multi-instrument and effects processor that you can use on stage when you perform. Whether you sing or play a keyboard, guitar, or another instrument, you can use MainStage when you perform live.

Using a USB or MIDI keyboard controller, you can play a wide variety of software instruments, including pianos and other keyboards, synthesizers, strings, horns, percussion, and more.
Using an iPad, you can also play software instruments, and control other aspects of MainStage, using the Logic Remote app.
If you play electric guitar, you can play through virtual amps and use effects such as overdrive, reverb, and compression.
Vocalists, drummers, and other musicians can sing and play with multi-effects setups using a microphone.
If you’re using a Mac with a Touch Bar, you can use the Keyboard on the Touch Bar to play software instruments.

In MainStage, you organize and access your sounds in concerts. A concert can store all the sounds you’ll use in an entire performance or a series of performances. In a MainStage concert, individual sounds are stored as patches, and each patch can contain one or more channel strips, each with its own instruments and effects. You can add channel strips, choose channel strip settings, add instruments and effects, and edit their parameters to customize your sounds. You can even mix channel strips of different types in a single patch.

You organize patches for a concert in the Patch List, which includes grouping them into sets, which are folders where you can store patches you want to keep together.

Each concert includes a visual interface, called a layout, with screen controls that you use to modify your patches in live performance. Screen controls include keyboards, faders, knobs, buttons, pedals, drum pads, and other hardware controls and displays. You make connections between your MIDI devices and your MainStage concert by assigning hardware controls to the screen controls in the concert, then map the screen controls to channel strip and plug-in parameters, completing the connection so you can easily manipulate the parameters for each patch in the concert.

You can also map screen controls to actions, which provide the ability to select patches, control the Tuner or metronome, provide visual feedback, and perform other functions.

MainStage lets you quickly and easily make controller assignments and parameter mappings to speed your workflow. You can customize your layout to match the controls on your MIDI hardware, to optimize the use of available screen space, or in other ways that suit your needs.

MainStage for keyboards

If you perform using a USB or MIDI keyboard controller, you can play and control MainStage patches with software instruments using your controller. You can assign faders, knobs, buttons, and other controls on the keyboard controller to screen controls in your concert, and then map those screen controls to parameters in your patches. You can choose exactly the parameters you want to have at your fingertips for each patch and access them from your controller as you perform.

You can use MainStage with other MIDI controllers, including sustain pedals, expression pedals, foot switches, MIDI guitars, and wind controllers that send standard MIDI messages. You can also control external hardware synthesizers, and other software instruments using external instrument channel strips.

Using an iPad, you can also play software instruments, and control other aspects of MainStage, using the Logic Remote app.

MainStage for electric guitar and bass

If you play an electric guitar, you can use MainStage as a powerful, customizable multi-effects processor. After you connect your instrument to your computer using an audio interface, you send your guitar’s audio signal to audio channel strips in your patches, where you can add effects including the Amp Designer and Pedalboard plug-ins designed specifically for use with electric guitar. You can also use EQ, compression, reverb, overdrive, and other effects in your guitar patches. You can control volume, effect blend, or expression with an expression pedal, and use a foot switch to select patches hands-free when you perform.

MainStage for vocals, drums, and other instruments

Vocalists and acoustic musicians can use MainStage by sending the audio output from a microphone connected to their computer to audio channel strips in their patches. You can use MainStage with Core Audio-compatible audio devices, such as audio interfaces and digital mixers, for input from instruments and microphones, and for audio output to speakers, monitors, a mixing board, or a public address (PA) system. In MainStage, you can access a wide range of effects in your patches.

Drummers can also use MainStage by sending the audio output from microphones to audio channel strips in their patches or by using drum pads or a virtual drum kit to control the Sampler, Ultrabeat, and percussion-oriented plug-ins.

MainStage in live performance

After you have created your custom patches in a concert, you’re ready to play. In Perform mode, you can select patches and start playing instantly. MainStage switches seamlessly between patches and sustains notes from the previous patch while you start playing the newly selected one. You can view patch names, parameter values, and audio output levels in real time, adjust concert-wide effects, and control other concert-wide settings.

By default, the workspace fills your computer screen, optimizing available screen space for your onscreen layout. You can also choose Perform in Window to have the workspace fill the MainStage window, while retaining access to the Finder and to other applications.

You can use MainStage with multiple MIDI controllers, microphones, musical instruments, and other music equipment. For time-based effects such as reverb and delay, you can set a predefined tempo, use MIDI input for tempo changes, or tap the tempo as you perform.

Using an iPad, you can also play software instruments, add patches, choose patch and channel strip settings, mute and solo channel strips, adjust Smart Controls, and control other aspects of MainStage, using the Logic Remote app.
